Closure Inside of a model factory

I'm trying to figure out why I'm getting the following error.

1. Tests\Unit\WrestlerTest::it_can_get_injured_wrestlers ErrorException: Undefined index: id.

/** @test */
    public function it_can_get_injured_wrestlers()
    {
        $wrestler = factory(Wrestler::class)->states('injured')->create();

        $injuredWrestlers = Wrestler::injured()->get();

        $this->assertTrue($injuredWrestlers->contains($wrestler));
    }

$factory->state(App\Wrestler::class, 'injured', function ($faker) {
    return [
        'status_id' => function(array $wrestler) {
            factory(App\WrestlerInjury::class)->create([
                'wrestler_id' => $wrestler['id']
            ]);

            return 3;
        },
    ];
});
